Perhaps you should get into battalion before thinking about career opportunities after CSOR. Focus on getting through your training, making the best out of your time in battalion and apply when you feel you are ready. If you do make it in, I'm sure you'll get an idea of what is a possibility for CSOR Operators.
There may not be any civilian careers that are directly related for CSOR Operator(Or Infantry), but your experience and skills developed during your time can be beneficial. Also, what you do post CAF will depend on what you are interested in, your education, etc. Going off your last post(Combat Engineer to LEO EOD), I'll just throw this in. If you become a Infantry Soldier and even if you become a CSOR Operator, you can not directly transfer into a LEO Tac Team, etc. It can be a possibility if you become a Police Officer, and get your time in.
You will get out of the Army what you put in. If you are a good troop, show leadership, etc courses and opportunity will come your way. If you hide from work, complain, put in minimal effort you won't get much.
Also, it's R22eR, or Royal 22e Régiment not r22r.
